Neosartorya fumigata is most commonly known as Aspergillus fumigatus and is the predominant cause allergic and invasive aspergillosis. The fungus is a primary pathogen of the sinuses, lungs, damaged skin, and subcutaneous tissue. It has the ability to spread to other organs including the brain. The medications used against
Aspergillus fumigatus are azoles like voriconazole, however the fungus is beginning to build resistance to the drugs. In fungus the synthasis of chitin is an essential component of the cell wall. The sugar nucleotide UDP-N-acetylglucosamine (UDP-GLCNAc) is essential in the production of this chitin. The enzymeUDP-N-acetylglucosamine pyrophosphorylase is the enzyme that is essential in the production of the sugar nucleotide (UDP-GLCNAc). In conclusion, this enzyme is a key target when it comes to the Aspergillus fumigatus disease. The general idea is to inhibit the enzyme, which will stop the production of the essential sugar nucleotide, then no chitin will be made, and the cell wall will corrupt killing the fungus.
